The cell phone plan from company C costs $10 per month , plus $15 per gigabyte for data used . The plan from company D cost$80 per mont, with ulimited data Rule C gives the monthly cost , in dollars , of g gigabytes of data on Company C’s plan. Rule D gives the monthly cost , in dollars , of using g gigabytes of data on Company D’s plan
1. Write a sentence describing the meaning of the statement C(2)=40
2.Which is less C(4) or D(4). What does this mean
3. Which is less C(5 ) D(5)
4. For what number g is C(g)=130
5. Draw tge graph of each function

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!

8.3 and the 3 is repeating

hope this .
